Some work out of our laboratory – led by graduate student Robert Danczak – was recently published in the journal Microbiome. Here, we sampled groundwater in aquifers across central and southern Ohio and, using assembly-based metagenomics – recovered genomes from many phyla within the CPR. To place these results in a larger context, we subsequently performed a meta-analysis of all available CPR genomes to assess their carbon processing potential, revealing phyla-specific trends. These results reveal that CPR are seemingly ubiquitous in groundwater systems, and play key roles in carbon and nitrogen cycles in these environments. See the publication here for more details.
